听一分钟英文：Global Warming-全球变暖（在线收听）

Global warming is the biggest problem in the world today. Everyone know about it but not everyone is trying to stop it. Many world leaders are more interested in blaming other countries for the crisis. Countries like China, India and Russia say they will not act unless America takes more action. America says it will not act until other countries take more action. It seems a little childish that leaders are acting in this way. The future of our world is at risk and governments can only argue with each other. Many presidents and prime ministers tell us that technology is the answer. They say future scientists will find solutions to save the planet. This is a big gamble. I hope they are right. I don’t believe them, so I’ll continue switching off lights and recycling.
